Preface: No idea what the video is about. It's well done, but I'll be damned if I can extract an inkling of a deeper meaning from it. Colors are nice, the style is appealing, and I dig the music.
That being said, I just find it so cringe-worthy that the two people who liked it only cited animated boobs as the component they liked. I mean, know they are being humorous, but I just think that is super reductive and perpetuates negative thinking across YouTube's age demographic.
Like said, I could be wrong in assuming there is a deeper meaning behind it, and maybe it really was meant to reach a certain group of people who enjoy anime nudity and THAT was it's sole purpose; I just think it is crude to assume that stance, and say "It has everything that makes a video great; boobs" to a hoard of 9 to 15 year-olds.
